Any Qt support for building strings from lists?

[feraudyh]

Hi,
The following code seems to work,

QString aString;
    QTextStream out(&aString,QIODevice::WriteOnly);
    out << 1;
    out << "+";
    out << 2;
// and so on...
    qDebug()<<aString;

QString aString;
    QTextStream out(&aString,QIODevice::WriteOnly);
    out << 1;
    out << "+";
    out << 2;
// and so on...
    qDebug()<<aString;

To copy to clipboard, switch view to plain text mode 

But I'd have to be convinced that it doesn't keep on concatenating and reallocating wastefully
Thanks anyway.
